- Cached Read Price: $0.500 per 1M tokens.
- Write Surcharge: $0.00 (automatic caching with zero write penalty).
- Minimum Cache Prefix: 1,024 tokens.
- Amortization Rule: Immediate net savings from first cached read call.
MiniMax: MiniMax M3 Caching Profile-80% read discount
- Cached Read Price: $0.060 per 1M tokens.
- Write Surcharge: $0.00 (automatic caching with zero write penalty).
- Minimum Cache Prefix: 1,024 tokens.
- Amortization Rule: Immediate net savings from first cached read call.
Batch API 50% Discount Offload vs Real-Time SLA
Asynchronous Batch APIs cut total token expenditures in half (50% off input and output) in exchange for non-realtime execution (up to 24-hour turnaround SLA).
| Model / Architecture | Standard Input / Output | Batch 50% Off Input / Output | Turnaround SLA | Optimal Use Cases |
|---|---|---|---|---|
| OpenAI: GPT-4.1 | $2.00 / $8.00 | $1.00 / $4.00 (-50%) | 24 Hours max (typically 30m - 2h) | Bulk evaluation, dataset labeling, background summarization |
| MiniMax: MiniMax M3 | $0.30 / $1.20 | $0.15 / $0.60 (-50%) | 24 Hours max (typically 30m - 2h) | Offline document translation, embedding backfills, test suites |
